Universal Apps -vs- Windows Store Apps

Question

Writing in C++ XAML and DirectX and targeting a Universal App though the main target is full up Windows 10. I am wondering what has changed in Universal Apps (if anything).

I would Love to have a Universal App over a desktop app. However I have some odd requirements and I am wondering if these are accounted for in Universal apps:

1) The device is multimon and I need the app on both screens. The screens are 1920x1080 and stacked on top of each other. A single desktop app is currently doing this by running in 1920x2160 resolution.

Q1) Can a Universal app scale to 1920x2160?

Q2) Can a universal app have two windows. One on each screen.

My questions are unusual and I am fine if the answer is wait until \\build conference is over..

I've been recommending that session frequently. Users expect multiple windows in the desktop environment, so it's really important that devs understand how to do that.

The app can't force itself on the user as you're looking for, but kiosk modes are about the system configuration forcing app behavior. It may be possible for system configuration to control the layout as you'd like. Since this is a system configuration question
rather than a dev question you'll be better off asking about kiosk specific configurations in the TechNet forums or in the embedded Windows forums.

This is similar to a dual screen KIOSK. I loaded up the sample and it was not obvious how to get the second Window to the other screen. Likely user error. Also the sample mentions that the user initiates the creation of the second Window
and I am hoping to get this second window at system boot without user interaction. Thoughts?

"This session will cover an overview of the Windows navigation model, taking those concepts and showing how this is built
from the basics up to multi-window applications running in both immersive and desktop mode."

Full link and more context below. Does this mean my Universal App can have a desktop mode much like IE? Do I need
to wait for the \\build session?

Our use is a KIOSK with two screens and the user will not be able to move the Windows (Or even know they are running Windows).

Navigation and Windowing in Universal Windows Apps

In Windows 10, your creation can end up running on anything from a highly specialized hardware with limited user-interaction
displaying only one application view at a time (such as a fitness band), to a general purpose system with touch, mouse, keyboard, and high-DPI monitors displaying multiple applications and application views simultaneously. Throughout this world the user expects
an intuitive and familiar model for not only navigating inside your app but also for navigating between apps. This session will cover an overview of the Windows navigation model, taking those concepts and showing how this is built from the basics up to multi-window
applications running in both immersive and desktop mode.
